kShowmail

kShowmail is a KDE tool for watching for email on POP3 servers. Headers and complete email messages can be displayed, and email can be deleted without downloading. Filters can be assigned to detect known spam by header fields, and marked email messages can be deleted automatically. The information can be refreshed via timers, and a sound can be played when new email arrives. External programs like fetchmail/sendmail can be called via configurable menu entries or if new mail arrives. Spam complaints can also be sent via configurable menus.
